How do you handle badge failures during an event?
By deciding in advance that nobody is refused entry over a badge. Every check needs a manual route and every member of staff needs to know it, because a queue at a door costs more than an imperfect attendance figure ever will.
Decide the policy first
Before any equipment question, decide what happens when a badge does not read and someone is standing at a door.
The answer should almost always be that they go in, and the discrepancy is resolved afterwards. An event exists to let people attend, and a count is a means rather than an end.
Write that down and tell every member of staff, because in the absence of a policy people improvise, and improvisation at a door produces a queue.
The exception is where entry is genuinely restricted, and even there the answer is a manual verification route rather than a refusal.
What actually fails
The badge is bent or creased, which is what happens to a card worn on a lanyard all day. This is the commonest physical cause.
The badge is behind other cards in a wallet or a badge holder, competing with them.
The reader has lost its connection, which is a system failure presenting as a badge failure.
The badge was never good, which is why verifying the batch before the event matters more than any procedure on the day.
And the badge is fine and the person is presenting it wrongly, which a marked reading position on the reader solves.
The replacement bench
Keep a small station away from the doors with blank badges, a reader, and access to the system.
Replacement is then: read the new badge, attach it to the person's existing record, void the old identifier, hand it over. Seconds, and their history is preserved.
Voiding matters. A badge that stops reading intermittently and is still valid in the system is a badge that will be used by whoever finds it.
Keep a written log of replacements. It is the record that explains an odd attendance figure afterwards.
What staff need to know
Where the replacement bench is, so they can direct someone rather than diagnose.
That they must not spend time troubleshooting at a door. One retry, then let the person through and point them at the bench.
That a badge behind other cards is the first thing to try, since asking someone to take it out of the holder solves a real proportion.
And that a run of failures at one door means the reader rather than the badges. Two failures in a row is a signal, not a coincidence.
Frequently asked questions
Should someone be refused entry over a badge?
Almost never. Let them in and resolve the discrepancy afterwards, because a queue costs more than an imperfect count.
What is the commonest cause?
A creased badge worn on a lanyard, or a badge behind other cards in a holder. Both are physical and both are quick to check.
How many replacements should I expect?
It depends on the badge construction and the length of the event, so measure your own rate and use it to size the next one.
Do I need to void the old badge?
Yes. A badge that still resolves to a valid record is usable by whoever finds it, which is a real problem at a public venue.
